Joy Adamson (1910 - 1980)

Friederike Victoria "Joy" Adamson (née Gessner) was a naturalist, artist and author who lived in Kenya in the 1950s. After her husband, a game warden, shot and killed a lioness, Adamson rescued one of the orphaned cubs. She later wrote "Born Free" about raising the cub, named Elsa, and releasing her back to the wild. The book was an international best-seller and earned Adamson acclaim for her conservation efforts. She was murdered in Shaba National Reserve in Kenya in 1980; her husband, George, was murdered in 1989 in Kora National Park while rushing to the aid of a tourist (who lived) who was being attacked by poachers.
